Acne vulgaris is one of the most frequent reasons for consultation in Dermatology. It is a condition that affects almost universally, to a lesser or greater degree, adolescents and young adults. However, contrary to what many think, is not a disease at all uncommon in patients older than 25 years, since up to 40% of men and 55% of women have acne outbreaks. It is what we call adult acne.
Causes the appearance of acne
Acne is a process that is located in the hair follicle and which is caused by the interaction of four main factors: Local excess fat secretion, plug formation obstructing the follicle, colonization by Propionibacterium acnes bacteria and occurrence of inflammation.
The appearance of acne lesions is due to increased formation of sebum due to stimulation of the sebaceous gland, which in turn is explained by the increased production of androgens (male hormones) that occurs during puberty. Therefore, acne is very common during adolescence.
In girls the first cystic acne one year may start appearing before menarche. In boys usually starts a little later, around age 14, but usually lasts until 18-19 years.
However, particularly in women, acne can persist (persistent acne) or appear for the first time (late onset acne) from 25 years. This type of acne in adulthood may be associated with certain syndromes, such as Polycystic Ovary Syndrome (PCOS), which agree rule.
On the other hand, adult acne can be triggered or worsened by several factors: genetic predisposition, stress, fatigue, smoking, improper use of cosmetics or during the menstrual period. Clinically, usually predominates the presence of inflammatory lesions, often profound, especially in the lower third of the face and the face (chin and jaw area) "U".
Although acne is not (in most cases) a serious pathology, yes often it has a major impact on self - esteem and psychological well - being of the patient who suffers. In addition, certain injuries tend to leave unsightly marks or scars on the skin that are often difficult to remove. Fortunately, today we have effective treatments that control outbreaks and hide the marks.

In each case we explain what treatment options exist and see what is the most suitable. Many times we must combine several treatments or use a different dose to the usual. In addition, it is necessary to daily care tips and guidance on the proper use of cosmetics. We seek not only control acne, but to achieve beautiful skin.
